I recently built my first system in about 10 years (so long that the last system I built did not require a heat sink for the processor!). I have a c2d 6600 on an EVGA NF680i board with a Zalman 9700 cooler. I think I have the thermal past on a little thick but I'm not sure what a typical idle temp should be for this setup. I'm idling at about 29c with the fan on lowest, and 26c with the fan on highest. Any advice would be greatly appreciated. BTW, I'm using the past that came with the cooler, which is supposed to be about as good as Arctic Silver according to one review I read.
